[1] We utilize securities sold under agreements to repurchase to facilitate the needs of our customers and to facilitate secured short-term funding needs. Securities sold under agreements to repurchase are stated at the amount of cash received in connection with the transaction. We monitor collateral levels on a continuous basis. We may be required to provide additional collateral based on the fair value of the underlying securities. Securities pledged as collateral under repurchase agreements are maintained with our safekeeping agents. The collateral pledged on the repurchase agreements by the remaining contractual maturity of the repurchase agreements in the Consolidated Balance Sheets as of December 31, 2025 and December 31, 2024 is presented in the following tables (in thousands).

[2] FHLB Advances consist of an “Open RepoPlus” agreement with the FHLB of Pittsburgh. FHLB “Open RepoPlus” advances are short-term borrowings that bear interest based on the FHLB discount rate or Federal Funds rate, whichever is higher.  The Company has a borrowing limit of $1,115,189,000, inclusive of any outstanding advances and letters of credit. FHLB advances are secured by a blanket security agreement that includes the Company’s FHLB stock, as well as certain investment and mortgage-backed securities held in safekeeping at the FHLB and certain residential and commercial mortgage loans.  A portion of these advances, $28,000,000, are subject to interest rate swap arrangements as of December 31, 2025. See Note 18 for additional information.

[3] The federal funds lines consist of unsecured lines from two third party banks at market rates.  The Bank has a borrowing limit totaling $34,000,000, inclusive of any outstanding balances.  No specific collateral is required to be pledged for these borrowings.

[4] The Federal Reserve Bank Borrower in Custody (FRB BIC) Line consists of a borrower in custody agreement opened in January 2010 with the Federal Reserve Bank of Philadelphia secured by municipal loans maintained in the Company’s possession.  As of December 31, 2025, and 2024, the Company has a borrowing limit of $11,798,000 and $14,353,000, respectively, inclusive of any outstanding advances. The approximate carrying value of the municipal loan collateral was $21,827,000 and $25,750,000 as of December 31, 2025 and 2024, respectively.

[5] The Company renewed a $15.0 million revolving line of credit in December 2025 with an unaffiliated bank with a maturity date of January 1, 2027, subject to certain covenants. The line is subject to an unused fee on the unborrowed portion of the Line of Credit on a quarterly basis, equal to 0.25% of the unused amount of the Line of Credit, calculated on a pro-rata basis, payable within thirty (30)-days after the end of each calendar quarter. Interest on outstanding borrowings is payable at 3 month term SOFR plus 300 bps. No specific collateral is required to be pledged for these borrowings.

[6] The Company entered into an agreement with a counterparty that provides for the Company the right to obtain collateral from the counterparty depending on the value of the underlying derivative instrument. The value of the collateral obtained can fluctuate daily. A market interest rate is required to be paid on any collateral held. As of December 31, 2025, the Company is holding $3,320,000 of collateral, which is included in cash and cash equivalents on the Consolidated Balance sheet.

[7] In April 2021, the Company issued $10.0 million of fixed to floating rate subordinated notes that mature on April 16, 2031, unless redeemed earlier. The notes bear interest at 4% per annum through April 16, 2026 and subsequently pay interest at the 90-day average secured overnight financing rate, determined on the determination date of the applicable interest period, plus 323 basis points. The Company may redeem the notes, in whole or in part, on or after April 16, 2026, and at any time upon the occurrence of certain events, subject in each case to the approval of the Board of Governors of the Federal Reserve System (the “Federal Reserve”). Issuance costs associated with the notes totaled $131,000 and were capitalized and will be amortized over the life of the note on a straight-line basis, which approximates the effective yield method. As of December 31, 2025, the net unamortized issuance costs totaled $69,000. As part of the HVBC acquisition, the Company acquired a subordinated note issued by HVBC with a par value of $10.0 million and a fair market value of $8,873,000 on the date of acquisition. This note has a maturity date of May 28, 2031, and has a coupon rate of 4.50% per annum through May 28, 2026. Thereafter, the note rate is adjustable and resets quarterly based on the then current 90-day average Secured Overnight Financing Rate (“SOFR”) plus 325 basis points for U.S. dollar denominated loans as published by the Federal Reserve Bank of New York. The Company may, at its option, at any time on an interest payment date, on or after May 28, 2026, redeem the notes, in whole or in part, at par plus accrued interest to the date of redemption. The carrying value of the note as of December 31, 2025 and 2024 was $9,717,000 and  $9,358,000, respectively.

[8] In December 2003, the Company formed a special purpose entity (“Entity”) to issue $7,500,000 of floating rate obligated mandatory redeemable trust preferred securities as part of a pooled offering.  The rate was determined quarterly and floated based on the 3-month SOFR plus 2.80 percent.   The Entity may redeem them, in whole or in part, at face value after December 17, 2008, and on a quarterly basis thereafter.  The Company borrowed the proceeds of the issuance from the Entity in December 2003 in the form of a $7,500,000 note payable.  Debt issue costs of $75,000 have been capitalized and fully amortized as of December 31, 2008.  Under current accounting rules, the Company’s minority interest in the Entity was recorded at the initial investment amount and is included in the other assets section of the balance sheet.  The Entity is not consolidated as part of the Company’s consolidated financial statements. The $7,500,000 note payable is subject to an interest rate swap arrangement. See Note 18 for additional information.
